Noob Question about how to run this

Hey all,

First and foremost I think this mod looks amazing and I totally want to use it but I dont know how to work it (I'm a mac user). I've checked out some other threads before saying that I need to download Mod manager and mono but I downloaded both, followed the steps as shown here:

(old / alternative guide below) Originally Posted by ss4_linkFirst download the original ModMan file and then the latest version of mono.

Now once that is done install Mono and then open up Terminal (it should be in the applications folder or the Utilities folder). Once that is done and you see the string that has your user name type "mono" and then drag and drop the ModMan.exe into the window and it should show the file path. Press enter and it should run, it might take a while to load at first but it will run.

It will ask you to make a path to Heroes of Newerth, at the moment the only way for that to work is to use the string "/Applications/Heroes of Newerth.app" and that has to be put in manually.

But for some reason when I follow all this I keep getting an error that looks like this:
129-97-235-234:~ BrianChan$ /Users/BrianChan/Downloads/HoN_ModMan.exe
-bash: /Users/BrianChan/Downloads/HoN_ModMan.exe: cannot execute binary file

EDIT: Hi as you've told me I downloaded a java hon mod manager called All-In Hon Modmanager from here: http://sourceforge.net/projects/all-inhonmodman/ but for some reason it keeps saying it cannot auto detect HoN or mod folders. Do you know how i can tackle this problem please? And as for the fixed xUI version, would that be xUI v 1.3 from the front page? Thanks so much in advance and sorry for the noob questions! ><"
